Sweet Potato Cakes with Tomato & Soy Sauce

The aroma of sweet potatoes roasting always takes me back to my grandmother’s kitchen. She had a small, unassuming oven that somehow produced the most incredible baked goods. While she usually made sweet potato pie, one time she experimented with savory sweet potato cakes, a departure from her usual Southern fare. I remember being skeptical, but one bite, and I was hooked. The sweetness of the potato, balanced with savory spices, was a revelation. This recipe reminds me of that childhood discovery, a delightful dance between sweet and savory, comfort and adventure.

Recipe Overview

Total Time: 45 minutes
Servings: 4
Yields: 12 cakes
Dietary Type: Vegan

Ingredients

2 large sweet potatoes, about 500g total weight
2 garlic cloves, crushed
1 small green chili pepper, chopped
2 sprigs cilantro, chopped
1 tablespoon soy sauce or 1 tablespoon Braggs liquid aminos
All-purpose flour, for shaping
Vegetable oil, for frying
Sesame seeds, for sprinkling

For the Soy and Tomato Sauce:

2 teaspoons vegetable oil
1 garlic clove, chopped finely
¾ inch gingerroot, chopped finely
3 tomatoes, skinned and chopped
2 tablespoons soy sauce or 2 tablespoons Braggs liquid aminos
1 tablespoon lime juice
2 tablespoons fresh cilantro, chopped

Equipment Needed

Food processor (optional, for grating sweet potatoes)
Mortar and pestle
Large mixing bowl
Wide skillet
Paper towels

Instructions

Prepare the Soy & Tomato Sauce: Heat 2 teaspoons of vegetable oil in a wok or medium saucepan over medium heat. Stir-fry the finely chopped garlic and ginger for about 1 minute, until fragrant. Be careful not to burn the garlic.
Add the chopped tomatoes to the wok. Stir-fry for another 2 minutes, allowing the tomatoes to soften slightly.
Remove the wok from the heat. Stir in 2 tablespoons of soy sauce (or Braggs liquid aminos), 1 tablespoon of lime juice, and 2 tablespoons of chopped cilantro. Set the sauce aside and keep warm. You can gently warm it before serving, if needed.
Prepare the Sweet Potatoes: Peel the sweet potatoes. Grate them finely using a box grater or quickly with a food processor fitted with a grating attachment.
Make the Paste: Place the crushed garlic, chopped chili, and chopped cilantro in a mortar. Crush with a pestle to create a smooth paste. This step releases the essential oils and intensifies the flavors.
Combine Ingredients: In a large mixing bowl, combine the grated sweet potatoes with the garlic-chili-cilantro paste. Stir in 1 tablespoon of soy sauce (or Braggs liquid aminos). Mix thoroughly until all ingredients are well combined.
Shape the Cakes: Divide the sweet potato mixture into 12 equal portions. Lightly coat your hands with all-purpose flour to prevent sticking. Dip each portion into flour, ensuring it’s lightly coated on all sides. Gently pat the floured portion into a flat, round patty shape, about ½ inch thick.
Fry the Cakes: Heat a shallow pool of vegetable oil (about ¼ inch deep) in a wide skillet over medium-high heat. Ensure the oil is hot before adding the patties.
Cook the sweet potato patties over medium-high heat until they are golden brown and crispy, about 3-4 minutes per side, turning them once. Adjust the heat as needed to prevent burning.
Drain and Garnish: Remove the cooked patties from the skillet and drain them on paper towels to remove excess oil. Immediately sprinkle the hot patties with sesame seeds.
Serve: Serve the sweet potato cakes while they are still hot, with a generous spoonful of the prepared Soy & Tomato Sauce.

Expert Tips & Tricks

Sweet Potato Variety: While any sweet potato will work, using a variety with a vibrant orange hue will give your cakes a more appealing color.
Adjusting the Spice: The amount of chili pepper can be adjusted to your preference. For a milder flavor, remove the seeds from the chili before chopping. For extra heat, add a pinch of red pepper flakes to the sweet potato mixture.
Preventing Sticking: If the sweet potato mixture is too sticky, add a little more all-purpose flour, one tablespoon at a time, until it’s easier to handle.
Even Cooking: Ensure the oil is consistently hot for even cooking. If the patties are browning too quickly, reduce the heat slightly.
Make Ahead: The sweet potato mixture can be prepared ahead of time and stored in the refrigerator for up to 24 hours. Shape and fry the patties just before serving for the best texture.

Serving & Storage Suggestions

Serve these sweet potato cakes immediately while they are hot and crispy for the best texture and flavor. The Soy & Tomato Sauce complements the cakes beautifully, so don’t skimp on it! They make a fantastic appetizer, side dish, or even a light lunch.

Leftover sweet potato cakes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, you can pan-fry them again with a little oil until heated through and crispy, or bake them in a preheated oven at 350°F (175°C) for about 10 minutes. Microwaving is not recommended as it can make them soggy. The sauce can also be stored in the refrigerator for up to 3 days.

FAQs (Frequently Asked Questions)

Q: Can I bake these instead of frying them?
A: While frying yields the best crispy texture, you can bake them. Bake at 375°F (190°C) on a lightly oiled baking sheet for about 20-25 minutes, flipping halfway through, until golden brown.

Q: Can I make these ahead of time and freeze them?
A: Yes, you can freeze the cooked cakes. Allow them to cool completely, then arrange them in a single layer on a baking sheet and freeze. Once frozen, transfer them to a freezer bag for longer storage (up to 2 months). Reheat in the oven for best results.

Q: I don’t have a mortar and pestle. What can I use instead?
A: You can finely mince the garlic, chili, and cilantro and then mash them together with the flat side of a knife to release their flavors.

Q: Can I use a different type of chili pepper?
A: Absolutely! Feel free to use any chili pepper you like, such as jalapeño, serrano, or bird’s eye chili, depending on your preferred level of heat.

Q: Can I add other vegetables to the sweet potato mixture?
A: Yes, you can add other finely grated vegetables like carrots or zucchini to the sweet potato mixture. Just make sure to squeeze out any excess moisture before combining them.
